Ender 3 V3 KE/SE Auto Nozzle Cleaning Brush Mount

Important Note Consider remove the brush when you run the built-in self testing or bed mesh calibration. The z-offset result may be affected If your brush is too “tall” and block the extruder during the process. Version supporting calibration is also available. Credit This is a remix model, taking the base from Ender 3 V3 KE Nozzle-Cleaning Brush Mount [UPDATED V2] and the mount from Ender 3 V3 KE and SE automatic nozzle cleaning brush. The thumbscrew design was inspired by funbart's creation. You can view their original design here . Changes With side storage and handle at the front, I am not able to use both of the designer on my printer, so i remix them to suit my need. The position of the brush is the same (or close to) the position of Ender 3 V3 KE and SE automatic nozzle cleaning brush. Other parts needed A M4 nut is needed for the thumbscrew. Gcode Please refer to the original post . Working with Bed Mesh Calibration (v3 update) As I want to keep the bed mesh calibration in my start gcode, so I lowered the mount (v3), and modify the gcode accrodingly. I am not really familiar with gcode, so I may have kept some unnecessary step here, but here for anyone who want need it for reference.
